“A drone with footage showing Oak Road Playing Fields was found and it was confirmed that, as he had told police in interview, that he had flown his drone over them a couple of days before”
So PR recorded while using the drone. You cannot record audio with a drone but I wonder if he used his phone as a recording devise to record LE’s conversation. He could have attached it to the drone. I easily researched this so I am sure he could have. I guess LE did not see the drone or there was more than one because other folks would have been interested in seeing what was going on? What is LE protocol when they see drones flying above crime scenes or searches in progress? We have seen and heard how the suspect will try to interject themselves in the investigation by searching, offering to help, going to press conferences but using a drone keeps them involved but out of eyesight.
